2020-3-7 Limestone, a kind of natural mineral resource, is a sedimentary rock formed by inorganic remains such as shells or bones. And people always see it in warm and shallow water fields. We all know that the main ingredient of limestone is calcium carbonate but sometimes it may also contain magnesium, iron or manganese affecting the Read MoreLimestone Powder: Uses, Price and Production »
Read MoreLimestone. Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO3)2.
